That's a good point. According to wikipedia, there are 3 different A15 chips already.

The iPhone 13 and 13 mini have 2.93ghz high power cores and 2.02ghz low power cores.

The iPad Mini 6 has the same 2.93ghz high power cores and underclocked 1.82ghz low power cores, I believe because of the extra heat from the larger screen.

The iPhone 13 Pro and Pro Max have higher clocked 3.23ghz high power cores and the same 2.02ghz low power cores as the regular iPhone 13.

The iPhone Pro's also have the extra 2GB of ram compares to the others and the iPhone 13/13 Mini are the only ones with the 4 core GPU rather than the 5 core GPU.

All we know now for sure about the iPhone 14 and 14 Plus are that they will have the 5 core GPU. We will have to wait for a hands on to know more about the specifics of the A15 they are using.

That said, I doubt that they will have the underclocked low power cores that they iPad Mini 6 has so I think the path of least resistance is for them to take the same A15 from the 13 Pro, with more RAM and overclocked high power cores, and just keep using it in the iPhone 14.

Otherwise they have to introduce a fourth A15 variant which seems like more work than using one they already are manufacturing.

I don't know shit about CPU manufacturing though so I am mostly just talking out of my ass.
